When implementing the method, the received signal is processed in the low-frequency range of noise emission. Analysis of the spectral composition of the signal is carried out with determination of the frequency of the maximum harmonic at each of the successive instants of time and the harmonic frequency is compared to each previous and current time. It is decided that object increased (decreased) speed of movement if harmonic frequency increased (decreased).
